Cercetări experimentale privind comportarea sistemelor pentru faţade, expuse la acţiunea focului / Experimental research on the behavior of systems for facades exposed to fire action [in Romanian]
Rezumat/Abstract. Visually, it is often the goal of any architecture to define a personality or individual character through the design of the façade. This face or skin, wrapped to the structural frame beneath, is often key to an architect's desire to evoke our emotions, instilling a sense of grandeur as if each new building were an artist's sculpture. In recent decades the desire for taller structures and, particularly, those that are competing for recognition to be among the tallest, if not the world's tallest, is reason to review the fire safety issues related to façade or curtain wall design. Additionally, due to the crea tivity of a rchitects, new and unique faça de designs a re continually appearing. The risk of fire spread through articulated elements of the façade or vertically around the façade via the mechanism of flame leap, poses new concerns for the newest class of super highrise structures. Our understanding of fire and its mechanisms of spread in buildings no longer eludes us, however, the risks of fire spread related to super high-rise buildings and the façades that define their character has not been well examined. Current code practices recognize the successful record of fully sprinkler protected high-rise buildings and only require that the void space between
the curtain wall and the floor slab be resistive to fire spread using a perimeter fire barrier system.
